Abstract

Private vehicles such as cars and motorcycles are crucial modes of transportation for the movement of goods and people. With technological advancements, car manufacturers offer a wide range of vehicles. Therefore, prospective buyers face challenges in selecting a vehicle that best suits their preferences and criteria. To tackle the issue, this study develops a practical decision support system (DSS) as a user-friendly tool for buyers, with theoretical contributions in the form of a more adaptive TOPSIS application and systematic analysis in car selection. This study focuses on collecting car-related data using 12 criteria, such as price, fuel consumption, safety, and design. The TOPSIS method is then normalized to ensure a fair and objective comparison between criteria. The results show the top alternative ranking, Suzuki 2002 (closeness score of 0.7089 in position 1), and the SUS test result of 85.6, indicating that the system is easy to use and capable of providing recommendations that align with user preferences. Therefore, this study highlights that the TOPSIS method can be an effective tool in supporting car purchase decision-making and making it easier for prospective buyers to choose the car that best suits their needs.

Abstract

Election violations in the form of casting more than one vote constitute a serious offense that undermines democratic integrity and the principle of one person, one vote, one value. This crime becomes more severe when it is intentionally committed by individuals who possess access and authority within the voting process. This study aims to analyze the factors causing election crimes involving multiple voting during the voting process and to examine their law enforcement based on Decision Number 99/Pid.Sus/2024/PN.Sdn. The research employs normative juridical and empirical approaches, with data collected through literature review and field research and analyzed qualitatively. The findings indicate that internal factors include the perpetrator’s intent, abuse of authority as a member of the Polling Station Working Committee (KPPS), low legal awareness and electoral ethics, and personal interests. External factors consist of weak supervision during voting, suboptimal polling station management, and a permissive culture toward election violations. Law enforcement against this crime was conducted through the Integrated Law Enforcement Center (Gakkumdu), involving the Election Supervisory Body, the Police, and the Prosecutor’s Office, resulting in a court verdict imposing a sentence of three months’ imprisonment and a fine of IDR 5,000,000 with one month subsidiary imprisonment. This decision provides legal certainty and reinforces the integrity of election administration.     Pelanggaran Pemilu berupa pemberian suara lebih dari satu kali merupakan perbuatan yang mencederai integritas demokrasi dan prinsip one person, one vote, one value. Tindak pidana ini menjadi semakin serius apabila dilakukan dengan sengaja oleh pihak yang memiliki akses dan kewenangan dalam proses pemungutan suara. Penelitian ini bertujuan untuk menganalisis faktor penyebab terjadinya tindak pidana Pemilu berupa pemberian suara lebih dari satu kali pada waktu pemungutan suara serta penegakan hukumnya berdasarkan Putusan Nomor 99/Pid.Sus/2024/PN.Sdn. Metode penelitian yang digunakan adalah pendekatan yuridis normatif dan empiris, dengan pengumpulan data melalui studi pustaka dan studi lapangan, yang dianalisis secara kualitatif. Hasil penelitian menunjukkan bahwa faktor internal meliputi unsur kesengajaan pelaku, penyalahgunaan kewenangan sebagai anggota KPPS, rendahnya kesadaran hukum dan etika kepemiluan, serta adanya kepentingan pribadi. Faktor eksternal meliputi lemahnya pengawasan saat pemungutan suara, tata kelola TPS yang belum optimal, serta budaya permisif terhadap pelanggaran Pemilu. Penegakan hukum terhadap tindak pidana tersebut telah dilaksanakan melalui mekanisme Sentra Penegakan Hukum Terpadu (Gakkumdu) yang melibatkan Bawaslu, Kepolisian, dan Kejaksaan, dan berujung pada pemidanaan oleh pengadilan berupa pidana penjara 3 (tiga) bulan dan denda Rp5.000.000,00 subsidair 1 (satu) bulan kurungan, sehingga memberikan kepastian hukum dan memperkuat integritas penyelenggaraan Pemilu.

Abstract

The Muhammadiyah Branch Management (PCM) and Nasyiatul 'Aisyiyah Branch Management (PCNA) of Kebakkramat are organizations that are active in social, religious, and cadre development activities in Karanganyar. The challenges of regeneration and strengthening cadre activities have driven the need for practical and relevant empowerment programs. These community service activities are carried out through creative economy training in the form of making liquid dish soap and ecoprinting as an effort to improve the skills and capacity of cadres. Liquid soap was chosen because it is a household necessity with broad business opportunities, while ecoprinting was chosen as an environmentally friendly craft skill that can be developed into products of artistic and economic value. The implementation methods included introduction, education, implementation, evaluation, and monitoring. The results of the activities showed an increase in the creativity and understanding of cadres in utilizing business opportunities based on practical skills. This activity also contributed to strengthening the association's independence and competitiveness and produced outputs in the form of scientific publications, documentation products, and potential intellectual property rights (IPR). This program is expected to be a strategic step in strengthening cadre capacity and supporting sustainable community empowerment.

Abstract

Abstract–The management of posyandu data in Majegan Village is still carried out manually. This causes health monitoring to be not optimal, especially in detecting stunting in toddlers. One of the efforts to overcome this problem is to provide a posyandu information system that can make it easier for posyandu officers to record and analyze fetal growth until toddlerhood and can detect symptoms of stunting. Through the implementation of Bayes' theorem in a web-based application, stunting symptoms can be observed earlier. Bayes' theorem calculates the values of the symptoms experienced by toddlers so as to obtain the results of probability numbers that can be used to predict stunting in toddlers. System design uses the waterfall method which goes through the stages of SDLC (System Development Life Cycle). After the system was developed, to test the quality of the application and the accuracy of naïve bayes in predicting stunting, two types of testing were carried out, namely black box testing and system usability testing (SUS). The black box test results show that the application functionality runs well with an error percentage of 0%, while the SUS test results show that the application has a usability level at Level B which means the application can be used and help users. Meanwhile, the results of the prediction of naïve bayes produced the model with the highest prediction of 60%.
